We'd like to welcome everyone to the Michelson Tools factory site , and thank everyone for being here today . My name is Paul Shafer , I'll be showing you around today . Please feel free to ask questions at any point during our tour , I'll be happy to answer questions for you .   Is it really necessary to wear all this protective gear ?   That's an excellent question . I'll bet your wondering why we ask you to wear hard hats and safety googles while you's in the plant . The reason is simple , we care about your safety and we want to ensure there are no injuries today . As you will see , to maintain a high level of safety , we also require all of our staff to wear similar protective gear .   How long will the tour take ?   It should take about twenty minutes to go through the main plant , and maybe another ten to take a look at the laboratory . All together our tour should last about half an hour .   Okay ...   Well , if you don't have any questions , shall we get started ? If you'll follow me , first I'll take you to the site of our semi-conductor system ...
